Upgrading an ASP. NET Core 2.0 project to ASP. NET Core 2.1.3X

At the end of the previous article ASP. NET Core Run error Http error 502.5 workaround, it is mentioned that the most recommended upgrade is to upgrade from 2.0 to version 2.1X.

Operation is as follows

The project example uses Https://github.com/52ABP/52ABP.School directly as an object, after all, he happens to be the version of. NET CORE 2.0.

The first thing to download is the SDK package.
Address: Https://www.microsoft.com/net/download
Download the latest version of. NET Core 2.1.

After opening the LTM.School project, right-click the project to locate the LTM.School.csproj file and change the target framework in the file tonetcoreapp2.1
After modification:

    <TargetFramework>netcoreapp2.1</TargetFramework>

The corresponding reference to the package packages is then modified.
Before modification

<ItemGroup>    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.3" />    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="2.0.1" />    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.1" />    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.0.0" />  </ItemGroup>

Currently according to Microsoft's update strategy, when upgrading, you can already upgrade directly from it to 2.1.3.

We need to modify it to:

  <ItemGroup>    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="2.1.1" />    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.1.1" />    <PackageReference Include="Microsoft.AspNetCore" Version="2.1.2" />    <PackageReference Include="Microsoft.AspNetCore.CookiePolicy" Version="2.1.1" />    <PackageReference Include="Microsoft.AspNetCore.HttpsPolicy" Version="2.1.1" />    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.1" />    <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.1.1" />    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.1.1" />  </ItemGroup>

Then close and save the LTM.School.csproj project file.
